The kernel defines 8 severities. Lets be compatible to these numbers so
our API will not have to be changes in the future.
This also causes LOG_ALERT to be added. It is not used, yet, but may be in
the future.
We also change the parameter type of severities to "unsigned int". Enum
variables can change types if new enums are added. We don't want that so
use a fixed type.

eloop.c and log.c use struct timeval to calculate time-diffs but
incorrectly use "-" instead of "+" as the value is already negative.
They also use unsigned integers so fix both occurences.

The new logger is much more powerful, allows online log-filter
modifications and precise debugging. We still avoid heavy file-operations
as we rely on the caller to forward stderr to a log-file and perform
log-rotations. However, we now provide a simple way to perform this
forward inside the application.

This makes things easier in the common case of
<some error> -> <log error> -> <goto error handler> - <do something with
errno>

We simply forward all log messages to stderr. We use syslog/prink-like severity
prefixes. Use systemd or alike to forward stderr to syslog, kernel-log or
similar.
